I am amused at the up and downvotes on your comment. Have an up vote from me :)
A 7.0 log10 lethality means that a process has reduced the number of harmful bacteria, like Salmonella, by a factor of 10 million, effectively killing 99.99999% of them
This is the same way they measure the time duration you need to hold poultry at 165°F for.
Here’s a fun thought experiment: egg whites collegiate (ie are considered cooked) at 150° F. To reach 7.0 log10 levels of salmonella killing you would have to either have to hold your eggs at this temperature for 72 seconds or cook them to a higher temperature and hold them there less long. I don’t know about you, but I like over easy eggs. The center of the yolk gets no where near 150.
I am a microbiologist, I can vouch this is correct. There’s the concept of infective dose, which is the number of pathogens required to infect a host.
Humans are exposed to pathogens on a regular basis. As long as the amount of exposure is not enough to cause illness, you’re in the clear. A 7-log10 reduction should get pathogens far below the infective dose, unless you’re eating like…a solid mass of Salmonella. Gross.
Now I’m going to sous vide some chicken breasts at 120°F this weekend, for science!
Edit: just remembered Clostridium species are more heat resistant and sporulate. Don’t want botulism. 140°F it is!

I imagine the texture will probably be… not great, lol.
Report back on your findings!
Oh, it’s 100% gonna be nasty. I’ll make a post and tag you.
